The death toll is set to rise with numerous people still missing in Texas after the storms slammed the states during the Memorial Day weekend, causing record floods that destroyed hundreds of homes, swept away bridges, and even unearthed a coffin from a Houston cemetery.

At least two people have been killed in Houston in flooding that turned streets into rivers and led to nearly 1,000 calls for help in the fourth-most populous city in the country, officials said on Tuesday.
